Currently, Spark cannot push cast predicates down to Iceberg. For example, the following query performs a full scan:
SELECT * FROM orders WHERE to_date(date_key) = '2026-04-26' -- date_key is a string partition column;This is a regression compared with Parquet tables, where Spark can push down this predicate.
